The Grampian police force has confirmed that an emergency flight did take off from Aberdeen airport to attend to an ill baby during climate change protests this morning.

Grampian Ambulance Association told protestors Plane Stupid that no delay was suffered as a result of their action. The campaign group said: "We're really pleased that no one's life was put in any jeopardy because obviously that's not what our organisation is about."

Members of the Scottish branch of Plane Stupid had broken through the fence at the airport in the small hours and set up a mini golf course and a camp, using Harris fences and locks to build the small construction on one of the runways. They phoned and announced their presence to police and airport authorities at 3.30am this morning.

The police arrived and began negotiations, reportedly telling the protesters that the runway was needed for emergency medical treatment, including that of a small baby. The protesters, not wanting to put lives at risk, voluntarily unlocked themselves and went into police custody.

However, when someone from Plane Stupid made a call to the emergency unit of Aberdeen hospital, they were told by the press officer that the hospital did not know about any transfers this morning, and that they had their own helipad that they used for emergencies. Grampian police later confirmed that a flight had taken off to attend an ill baby.

The protesters, who included Dan Glass, the man who once superglued himself to Gordon Brown, as well as other young activists and local residents, were highlighting the end of the National Planning Framework consultation by the Scottish government, which they claim has "involved very little consultation" and which may allow the expansion of all Scotland's airports, as well as permitting more road-building. An announcement is expected this week.

They're also convinced that the expansion of Aberdeen airport in particular is due to Donald Trump's golf course plans nearby – which explains the golfing attire. And the best banner of all? Nae Trump Games with Climate Change. Plane Stupid are a very busy group, so this will not be the last we hear of them.
